GOOGLE TARGETS JULY 17 FOR GEMINI 3.5 PRO AFTER SCRAPPING THE ORIGINAL BUILD AND STARTING FROM SCRATCH Google DeepMind is aiming for July 17 as the general availability date for Gemini 3.5 Pro. The date matters because it lands on the same day DeepSeek plans to graduate its V4 family from preview to official stable release, setting up a direct clash between two of the most anticipated model releases of the year. The backstory is messier than the launch announcement will make it sound. Google originally promised Gemini 3.5 Pro at its I/O conference in May. It missed that deadline. During the delay, the company made the decision to scrap the base model it had been working on and rebuild from the ground up, which internal sources attributed to quality concerns that more tuning was not going to fix. Several senior researchers left the team during the delay period. What comes out on July 17 — if the date holds — is described as a genuinely new architecture, not a patched version of what already existed. Google says it targets the same benchmark tier as the strongest models currently available, explicitly built to challenge GPT-5.6 Sol and the top of the Anthropic lineup. Whether it delivers is an open question. The pressure is real and the timeline has already slipped once.
